cornstone, the lower of which is about 12 feet thick. The strata are 

 said to dip regularly towards the centre of the hill at an angle of 

 about 7°. 



The coal-field is represented to have the form of the figure 8. 

 The strata are said to be about 150 feet thick, and to dip towards 

 a common centre at an angle of from 3 to 5 degrees. Three beds of 

 coal have been discovered, varying from 1 foot 7 inches to 2 feet 

 6 inches in thickness, but the coal is of inferior quality to that of 

 the Titterstone Clee Hill. 



Three faults are described, and stated to range nearly parallel to 

 each other, and to traverse the coal measures in a north easterly di- 

 rection. One of them, the author observes, is marked by a dyke of 

 basalt connected with an overlying mass of the same rock. It is 13 

 yards in horizontal thickness, and though the wall of the dyke is so 

 hard as to require to be blasted, yet the coal is not in the least 

 charred. 



The overlying basalt is shown to form the two highest points of 

 the hill, one of them being 1800 feet above the level of the sea, 



and the other 1600.

Jan 21, 1834. — Read the description of a new species of the 

 genus Chamceleon, by Mr. Samuel Stutchbury, A.L.S., Curator of 

 the Bristol Institution. 



This new species of Chamceleon, to which Mr. Stutchbury has given 

 the name of cristatus, from its peculiar dorsal crest, supported by 

 the spinous processes of the vertebrae, — by which character the ani- 

 mal approaches the Basilisks, — is from the banks of the riverGaboon, 

 in the western region of equinoctial Africa, and was presented, along 

 with specimens of other reptiles from the same country, to the mu- 

 seum of the Bristol Institution, by Messrs. King and Son of that 

 city. The colour of the body is ash-grey, with a dark patch upon 

 the anterior and superior part, giving off inferiorly two or three 

 bands : the posterior part marked with orange and dark-coloured 

 reticulate lines : the edge of the dorsal crest and tail spotted with 

 the same dark colour. Mr. Stutchbury gives the following differ- 

 ential character of the species. 



C. cristatus, superciliari occipitalique carina elevata et crenulata, 

 caudae anteriori parte dorsique apophysibus elongatis forma 

 cristas dorsalis, squamis fere rotundis subaequalibus. 



Read also part of a paper by Mr. Robert H. Schomburgh, en- 

 titled " A Description of some Trees, remarkable for their size or 

 age, in all parts of the world, but with particular respect to a Silk- 

 cotton Tree {Bombax pentaphyllum) near the town of the Island of 

 St. Thomas in the West Indies." 



A fine specimen of the Squacco Heron (Ardea comata), shot lately 

 in Hampshire, was exhibited at the meeting, as well as specimens 

 of a number of rare birds from Senegal, Mexico and Chili. A copy 

 of a large work on the plants of the country around Rio de Janeiro, 

 entitled " Flora Fluminensis," was presented for the Society's Library 

 by General Oliveira, F.L.S.
